Application filed March 23, 1914, Serial No. 826,757. Renewed December 30, 1915.

To all 'Lv/wm t may concern.'

Be it known that I. Anon-Prins S. Dennis, a citizen ot' the United States. and resident of Lakewood, Cuyahoga county, State of Ohio. have invented certain new and useful Improven'ient-s in Type-TViitinc ll'lachincs, ot which the following is a sliieciticat-ion.

The present invention relates to imlfn'ovements in vtypewriting machines and particularly to asupplemental writing or tally strip attachment for such machines. The, object of the invention is to provide an attachment which can be easily applied to a t'viprewitingr machine and by means oi" which a supplemental. writing such as a duplicate of the whole or a part of the primary writingr or a tally strip may be prepared when desired, and the parts of which attachment will be practically independent of the recordinc` devices of the. typcwritinay machine,

so aS not to interfere with the ordinary use ot such parts. the supplemental record, however, beingl made simultaneously with the actuation of the kevs manipulated to produce the primary record on the typewritinp; machine.

lVliile the improved attaclmient is adapte'd for use with various styles of typewriting machines, it has, inthe aeconipanyinev drawings, been shown applied to a machine of the'iront strike type or class. The particular form of machine illl'istrated is ot' the Underwood model, but as the attachment is adapted for use with other forms of type- WritingY machines the detail construction of such machine is unimportant and therefore the form of the invention shown in the dran`Y` ings is to he taken as merely illustrativeof the principles of the invention and many of the parts are merely shown conventionally, it being understood that various changes wil be made in the applicatimi oi the invention to the different styles of typewriters.

Fig. S) illustrates the supplemental sheet ilieedinc; means, being' substantially a section on the line 9--9 of Fig.

Referring` to the drawings, A designates the frame of a typewriting' machine in which are suitably supported a series ot' type bars B which are connected as l: v levers C with key levers D provided at their outer ends with numeral keys E or letter keys F in the ordinary manner. rihe type bars l), are adapted to cooperate with a rotatable platen (i which is mounted in a suitable carriage adapted to have a step-by-step motion. in the direction oil the length of the platen` under the control of an escapement Il which isA actuated by the keys E, F. As previously noted, thel parts referred to may be of any preferred or well known construen tion and therefore are illustrated more or less conventionally.

The improved attachment is secured to the rear 'face of the trame A of the typewriting machine and.- in the embodiment olf the invention illustrated. comprising the trarne side nien'ibers 25 which are provided with ears or lugs 9S. the slots-97 of which receive screws Q-i secured in cross plates or members 1G, lo of the typewriter vframe Si. The side plates` Q5 are provided with rearwardly and upwardly curved extensions QG to thc upper ends of which is secured a stationar)v track rail 27. A similar track rail is supported on the upper ends olj short posts or studs 25a rising, Jfrom the members and between said rails is mounted a supplemental record sheet platen carriage latter falls to its original position.

end plates 32, 33 and one of these gudgeons is provided with a hand wheel b y which the platen may be manually turned as desired, and the other gliulgeon, indicated by 89, carriesa ratchet 3G which has in cooperation therewith a pawl 3T `that is pivotally supported on an arm 38, this arm being pivotally mounted on lthe gudgeon 39 (see Fig. 9). A leaf spring -h'lacts to hold the pawl l'in engagement with the ratchet 36 and a spring d1 coi'inecting the arm 38 with the carriage end plate 33 acts to hold said arm and the pawl thereon in the posimovement of the arm 3S under the imiuence vcomprise a gravity latch or dog 4l which is pivotally connected with a. bracket 15, rising from the rear rail or bar 27, and extends into the path of a projection on the arm 38. As shown particularly in Figs. 5 and 7, the dog if-t is provided with a substantially vertical edge lia that normally extends into the path of the arm 38 and has its opposite edge or face 44') inclined or beveled. pin 46 limits, by engaging with the bracket L15, movement of the member 4% about its pivot in -either direction. carriage moves to the left in F'gs. Il and 5, the projection L13 on the feed arm 3S will engage the meml'ier 14- and ,turn it about its pivot so thatit will offer no obstruction to the continued leftward movement of the carringe. As soon as the arm 38 has passed from engagement with the member L141-, the

return movement of the carriage when the arm 38 comes against the inclined edge 44h, the member 42,4, will be held from turning by contact of the pin A1-6 withV the bracket and the arm 38 will be cammed downward,

thereby causing the pawl 37 to turn the' -'ratehet 36 and 4platen 34C one step.'

'The paper used in the attachment may be.

in the form of one or more strips on spools 90 `which are'supported by an arm 88 depending from the rear rail 30 of the carriage. Two spools 90 are shown and these are carried by/a horizontal rod 89 that is centrally supported by the arm SS. The sti-ins pass from the drums 90 in front of the platen Sel and beneath pressure rolls 91, the free ends of the strips being extended upwardly and passing over yoke-like support 92. i

s the On the t3, or

- The pressure rolls 91 are mounted on a shaft 93, the ends of which are supported by curved arms 91 pivotally mounted, las at95, on the carriage end plates 32 and 33,

springs 96 being` provided for-holdingthe rolls J1 against the vplaten 34.

A series of type bars T9, fulcrumed on a member 78 connecting the side frames 25 of the attachment are adapted to cooperate with the platen 34 and a suitable ribbon is mounted as hereinafter described to produce a record on the strip or strips of paper on the platen. As shown, said type bars normally rest upon a 'suitable pad or rubber cushion SO carried by a properlycur-ved bar 81, the ends of which are secured to the trame of the attachment and said type bars are engaged by studs 81 at the upper end ofv lever arms B3, which lever arms are ful-A j crumed on. a cross bar or rod extending from one side plate 25 to the other. The forward edge of each lever 83 is notched so to provide a lipSG (see Fig. 2) with which adapted to engage a loop or eye at the rear end of a rod 21, the forward end of which is connected with one of the levers C of the typewriting machine. Normally, the. rods 21'are held in the elevated position shown in Fig. 2 so that they' are out of engagement with ythe levers S3 and therefore movement of the levers C incident to actuating the type bars B does not cause any moven'lent of the corresponding type bars 7S). The means for thus disconnecting the levers C and S23-comprise a bail 19, the ends of which are Connected to a rock shaft 18 that is mounted in bearing lugs 1T secured to the upper edge of the member 1G of the rear frame of the typewriter, and a spring 87 which lconnects said bail with a stud on one ot' the side plates 25. Toguide the rods 21 in their reciprocation and maintain them in proper relative, position screws 23 are provided, said screws extending through j the loops or eyes 22 at the rear ends of said rods and` into the bail19.

An arm 20 extending ujnvardly and rearwardly from the rock shaft 18 projects into' iis engage a groove 8 in said shaft, are provided for holding the arms at any desired position lengthwise of the shaft 3. Shaft 3 is adapt'- ed to rock m its supporting bearings 1, 2,

'to position a stop 5, thereon, opposite either of two-notches 6, 6" in the bearing 1, and said shaft is also movable longitudinaliv under the influence of a, coiled spring 7 tio engage the pin with either of the notches To enable the shaft to be readily adjusted as desired, it is provided at one end with an enlarged head 4. When the rock shaft 3 is adjusted as shown in the drawings With its pin. 5 engaging the notch 6 in the bearing 1, the rear ends of the arms 12 and 11 will be positioned so that as the typewriter carriagemoves said arms will be adapted to coperate with plates 56, 57 on the carriage of the attachment to conneet the two carriages so that they will move together and also enable the plates 14: and 15 to engage with the arm 20.

The plates 56, 57 are pivotally mounted on an angle bar 55 secured to the forward bar 31 of the carriage of the attachment and said plates are provided in their upper edges with centrally arranged notches 60, 61, respectively, the top edges of said plates being beveled or curved downwardly from said notches toward both ends. Springs 58 connect said plates with a stationary pin 59 and act to normally hold the pla-tes in horizontal position as shown in Fig. 5. To the front stationary carriage guide rail 28 is secured an angle plate 68, the vertical'tlang'e of which is beneath the. plates 56, 57. Notches 64, 65 are formed :in the plate 63 so that when the plates 56, 57 are positioned thereover said plates may rock about their supporting pivots in oppositionv "to the springs 58 to permit the disengagement of the arms 11,12, and the release of the carriage of the vattachment from the carriage rof the typewriting machine.

The ribbon for the printing devices of the attachment is carried by two drums 66, 67 secured on shafts 68 that are mounted in` bearings in brackets 66 on the carriage supporting rail. 28. The ribboiris Wound from the drum 67 onto the drum 66 past a guide 77, the feeding movement being derived from the travel of the carriage. As shown, there is secured to the lower face of the carriage member 31 a rack 70 which meshes with a pinion 71 on a vertical shaft 72 supported by the carriage rail 28 and aforesaid bracket 69. The shaft 72 also carries a pinion 73 which meshes with a gear 711, loose on the shaft 68 of the Adrum 66. On the gear 74 is pivotally mounted ay pawl 75 which eoperates with aratchet 76 on the drum 66. Therefore as the rack moves in one direction the drum 66 will be positively turned to draw the ribbon from the drum 67 and wind it upon the drum 66. During movement of the rack -70 in the opposite direction, the pawlwill slip idly over the teeth of the ratchet 76.

In the undersurface of the carriage rail 30 are formed 3 recesses 52, 53 and 53, cach adapted to receive a roll 51 carried by a rocker arm 47 fulcrumed on a bracket 48 ldepending from the rear stationary guide 27. e opposite end of the rocker arm 17 1s provided-wth a lip 49 which extends beneath a cavity formed in the rail 27 and ing that it is desired to employ the attach-- ment for recording amounts appearing only in certain columns, for example, the totals Of a. series of bills of charges which are being written on the typewriter, the totals being positioned adjacent the right hand edge of a sheet on the platen G. For this work it will be necessary to employ only the strip on the right hand drum or spool 9() (as viewed from the front of Vthe typewriter.) The operator will first adjust thc arm 1l` longitudinally ot the rock shaft Si so that its rear end will be adapted to engage the notch 60 of the plate 56 when the typewriter carv riage is advanced to the left to a point where the platen will be in position to receive the highest denominational order olf av Fig 3. '1"he typewriter will then be actuated to write the several items ot' the bill and as the caig'riage thereof comes into position to permit of the total being recorded in thc appropriate column the arm 11 will be positioned in the notch 6() ot the plate 56 and during the further movement of the platen G incident to writing the total both carriages willbe locked together and move in unison. As the arm 11 approaches the notch 60, in the above described movement of the typewriter carriage, it will engage the curved upper edge of the plate 36 and rock Said plate about its pivot, this rocking movement being permitted by the notch 61 in the angle plate 63. However, when the arln 11 has enteredthe notch 60 turning movement of the plate 56 in the opposite direction is prevented by the angle plate 63 and during the time that the two carriages are moving" rio 19 and the loops` 22 so that the latter pass over the lips S6 ol the levers S3. 'lheretore during the writing of the total jon the typewriting lmachine, the correspoinling` type bars 79 ywill be actuated to duplicate the record of such total on the strip on platen 34:. It the lett 'ard movement of the typewriter carriage is continued beyond the Width of the totals column, the carriage of `automatically actuated to feed said strip one step or line.

In the embodiment of the invention illustrated, two record strips are provided and ity will be seen that by inljusting` the arn'i l2 so that it will cooperate with the plate 57 in a manner similar to the mainier in which the arm ll` cooperates with the plate 56, it will be possible to duplicate on the` left hand strip (as viewed :trom the 'Front ot' the typewriter), items recordeds in one column or succession of columns on the` platen G and to record on the right hand strip dnlilicates oit items recorded in 4a sccond column or lsuccession ot columns on the platen G. lhe lett hand strip may, lor example7 serve to provide a duivilicate ot all items recorded by the typewriting4 machine while the right hand strip is employed only for recording duplicates ot totals. rillhe amount ot each feed movement or spacingof the strips .trom one line to the next may be less than that olthe line spacingA movementof the platen (l so that the lines on the strips may be relatively closer together than the lilies on the primary record.

When it is not desired to employ the attachmeiit, it is merely necessary to rock the shaft 8 so that the .pin 5 thereon will engage the notch 6ft in the bracket l when the arms 1l., 1Q, on said rod will be lifted above the topfoi". the plates 5G, 5T, and the cam plates lll and l5 will be lit'ted above the top of the arm 20 so that neither the carriage nor printing devices will be operative. The entire attachment with thc exception ot the shafts 3 and 18 and the parts carried thereby may be readily removed 'from the inachine by merely disconnecting the spring yST from the bail lll and raising` the supportingy plates 2;* so that the stems of the screws 2l will pass through slots O7. j
